Abstract
The utility model discloses a connecting pipe fitting of thin wall metal pipe, which comprises a pipe fitting seat 1, a seal ring, a metal pipe 6 and a pipe fitting cap 7; wherein, the end head of the metal pipe 6 is provided with a bell mouth 5; the pipe fitting cap 7 is socketed behind the bell mouth 5; inside the pipe fitting cap 7 internal screw tread 8 is arranged; an inner oblique mouth 9 of the pipe fitting cap matched with the bell mouth 5 is positioned at the back inner part of the pipe fitting cap 7; the outer wall of the pipe fitting seat 1 is provided with external screw thread 2 matched with pipe fitting cap 7; a seal ring 4 is positioned at the end head of the pipe fitting seat 1 connecting with the pipe fitting cap 7 through screw-threaded connection. The utility model has the advantages of reasonable and smart structure, low cost and tight connection. The utility model is mainly suitable for connecting pipes with diameter less than phi 40 and the pipe fittings are able to be made into connecting fittings of different specifications and shapes, such as straightthrough, teejunction, teejunction variable connection and straightthrough variable connection of various specifications, elbows of different specifications and angles, and various inner and outer tooth joints.
Description
Technical field
The utility model relates to a kind of connection pipe fitting, particularly a kind of thin-wall metal pipe connected pipe fitting.
Background technique
Aqueduct is a part extremely crucial in the building, very very long process has also been experienced in the development of aqueduct, enforcement along with China's policies of reform and opening to the outside world, national economy obtains to increase fast, cities and towns dwelling house, public building and tourist facilities are built in a large number, and hot water service and domestic water supply have been proposed new requirement.Quality problem is subjected to people's common concern, and requirements in water quality is also improved constantly, and under water factory's water supply quality situation up to standard, real arrival uses the water quality level of water spot very different, and its basic reason is the secondary pollution of aqueduct to transporting water.The aqueduct description of materials is numerous, so the selection problem to the aqueduct material has just become the most important thing, therefore, the superiority of Stainless Steel Tube also more and more significantly embodies, particularly wall thickness only is that the thin-wall stainless steel of 0.6～1.2mm is in the drink water system, water heating system and with safety, the water supply system that health is put in the first place, it is safe and reliable, hygienic environment-protecting, characteristics such as economic and practical are approved by increasing people, and it is best to be proved the water supply system combination property by engineering practice, novel, one of tubing of energy-conservation and environment protection type, also be the most competitive a kind of water-feeding pipes, will be to improving water quality, improve people's quality of life and bring into play unrivaled effect.Therefore, relevant expert's prophesy: building water supply tubing finally will return to the epoch of metal tube.According to external application experience, assert that in metal tube thin-wall stainless steel is one of best tubing of combination property.
At present, in industry using is clamp-press type pipe part and plug-in type pipe part comparatively widely, and thin-wall stainless steel clamp-press type pipe part, tubing must have enough thickness to come support tubes, must limit the wall thickness that can't further reduce tubing; And plug-in type, its pipe fitting complexity, cost height.
Summary of the invention
The purpose of this utility model promptly is to overcome the shortcoming of prior art, and a kind of thin-wall metal pipe connected pipe fitting simple and reasonable for structure is provided, and it connects closely, and is easy to install.
The purpose of this utility model is achieved through the following technical solutions: the thin-wall metal pipe connected pipe fitting, it comprises the pipe fitting seat, seal ring, metal tube and pipe fitting cap are provided with horn mouth in the termination of metal tube, the pipe fitting cap sleeve is in the horn mouth back, be provided with internal thread in the pipe fitting cap, the rear portion is provided with angle in the pipe fitting cap that mates with horn mouth in the pipe fitting cap, and the outer wall of pipe fitting seat is provided with the outside thread with pipe fitting cap coupling, termination at the pipe fitting seat is provided with seal ring, and the pipe fitting cap screws with the pipe fitting seat and is connected.
The termination of pipe fitting seat is angle or straight mouth.
Closely withhold the angle of the termination of pipe fitting seat or straight mouthful of horn mouth inboard that is provided with by the termination of seal ring and metal tube.
Seal ring is the seal ring of band gradient.
By top narration as can be seen, the utlity model has following advantage: rational in infrastructure, ingenious, with low cost, connect closely, be applicable to that mainly diameter connects less than the tubing of Φ 40, pipe fitting can be made the link of all size, shape., threeway straight-through, threeway as all size become connect, straight-through become connect, the elbow of all size angle, the inside and outside tooth joint of all size etc.
